add those changes.
then add (or subtract) from 34
then add (or subtract) from 34
Let's break it down step-by-step:
1. Initial price: Jackie bought the stock for $34 a share.
2. Daily changes:
- Day 1: -5
- Day 2: -2
- Day 3: +1
- Day 4: +3
- Day 5: -6
- Day 6: +4
- Day 7: +8
3. Calculate the cumulative change:
- Cumulative change = -5 - 2 + 1 + 3 - 6 + 4 + 8 = 3
4. Calculate the share of stock worth at the end of day 7:
- The value at the end of day 7 = Initial price + Cumulative change
- Value at the end of day 7 = $34 + 3 = $37
Therefore, the share of stock was worth $37 at the end of day 7.
Let's go step by step:
1. Calculate the cumulative sum of the daily changes:
-5 + (-2) + 1 + 3 + (-6) + 4 + 8 = 3
2. Add the cumulative sum to the initial price of $34:
3 + 34 = 37
Therefore, the share of stock was worth $37 at the end of day 7.
